Sun., Nov. 7, 1:30 p.m., Mary Priestley - This trail, named for Hugh Caldwell, philosophy professor and founder of the Sewanee Outing Club, was established just this summer by Sewanee Outing Program Director John Benson and his summer interns. The trail is located largely along the rim of Lost Cove with glimpses into the University's newly-acquired property. Meet at the Sewanee Market for this easy 2-mile hike.  Wear appropriate shoes on all of these walks. Risks involved in hiking include physical exertion, rough terrain, forces of nature, and other hazards not present in everyday life.  Picking flowers and digging plants are prohibited in all of the above-mentioned natural areas.
